Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Summary

Subungual melanoma, a rare cancer under the nail, is often misdiagnosed due to patient-attributed trauma, delaying critical diagnosis and treatment.

Pathology

Background:

Subungual melanomas are rare but frequently diagnosed late, correlating with advanced disease stages.
Patient attribution of subungual lesions to trauma is a common reason for diagnostic delays.
The role of trauma in subungual melanoma pathogenesis remains uncertain, potentially influencing presentation or susceptibility.

Observation:

A case study of an 86-year-old man with subungual melanoma is presented.
The patient's history of trauma and the lesion's clinical presentation initially obscured the diagnosis.
The diagnosis was slightly delayed due to these factors.

Findings:

Biopsy is crucial for diagnosing all nodular acral tumors.
The presented case highlights the diagnostic challenges in subungual melanoma.
The direct causal link between trauma and melanoma development is not definitively established.

Implications:

Emphasizes the importance of considering subungual melanoma in patients with acral lesions, even with trauma history.
Highlights the need for prompt diagnostic evaluation and biopsy of suspicious subungual lesions.
Suggests further research into the relationship between trauma and melanoma development in acral sites.
